In December 2015, the United Nations General Assembly designated 5 November as World Tsunami Awareness Day to promote a global culture of tsunami awareness.

Tsunamis are rare but they can affect a lot of people especially communities living in coastal areas. The 2004 Indian Ocean earthquake tsunami affected up to five million people in 15 countries. Tsunamis know no borders, making international cooperation key for deeper political and public understanding of risk reduction measures.

For the second year in a row, the World Tsunami Awareness Day will align with the International Day for Disaster Reduction and the "Sendai Seven Campaign" and will focus in 2017 on Target B of the Sendai Framework for Disaster Risk Reduction which aims at reducing the number of affected people globally by disasters.

UNISDR calls us to join their effort and spread the word about World Tsunami Awareness Day using main hastags #TsunamiDay2017 and #switch2sendai.
